Patent ES-215311-A1 (ES)
Title: Improvements in or relating to the smelting of zinc and lead-containing materials
IPC: C22B13/00
Filed: 1954-05-12
Abstract: Metalliferous materials containing substantial amounts of lead and zinc are smelted with carbonaceous material in a blast furnace, the charge and/or the air blown into the furnace being preheated to such an extent that a reducing environment is maintained throughout the smelting charge and the proportion of carbonaceous material in the charge is not substantially greater than would be required if lead compounds were omitted from the charge. The charge may be preheated to at least 600 DEG C. and the air to at least 500 DEG C. The constituents of the charge may be separately heated, the carbonaceous material to 800-1000 DEG C. and the remainder of the charge to 500-750 DEG C. A charge containing zinc enriched slag from a conventional blast furnace smelting of lead ores and lead sulphide concentrates may be treated, the lead forming, for example, 9-85 per cent of the total of lead and zinc. A suitable quantity of carbonaceous material to be used is equal to the sum of about 90 per cent of the zinc to be volatilized and about 20 per cent of the slag to be formed. The gaseous product resulting from the smelting operation withdrawn from above the charge level may be treated with a controlled amount of an oxygen-containing gas thereby raising the temperature of the products by oxidation of some of the carbon monoxide to permit their travel to a shock-chilling condenser without oxidation of zinc, the carbon dioxide content of the resulting gases being not over 12 per cent. Specifications 572,961, 682,176, 682,179, 686,542, 686,585, 686,589, 726,530 and 741,243 are referred to.

Title: Fluted lobular thread-forming members
IPC: B23P15/48
Filed: 1962-09-15
Abstract: A fluted thread forming member, such as a tap 15, for swaging threads in a parent body, is produced by extruding a blank 37 from wire stock to form a shank portion 18 which includes an odd number of flutes, the resulting convex tubular parts of the shank then being rolled between dies to form a thread. The radius of the resulting lobular threaded portions is smaller than the distance 43, Fig. 5, between the tip of a lobular portion and the work axis. Similarly, the radius of curvature of the roots is less than the distance between the axis and the root. A ram 61, Fig. 8, movable in a housing 49, forces the shank portion of the blank through a shaped die 53, an ejector 37 also being provided, and the subsequent rolling takes place between flat or curved dies.

Patent ES-298521-A1 (ES)
Title: Improvements in the treatment of polyester fibrous materials and films
IPC: D06M11/55
Filed: 1964-04-10
Abstract: Synthetic polyester filaments, fibres, and fabrics are treated with a compound containing at least one chemical group which confers some desirable property upon the surface of the treated material and at least one alcoholic hydroxyl group, e.g. a poly (oxyethylene) glycol of average molecular weight about 600, and an involatile strong acid, having a first dissociation constant of not less than 10-3 in water at 25 DEG C. and a boiling point above 250 DEG C. at atmospheric pressure, e.g. sulphuric acid, and heated to a temperature and for a time such that chemical groups derived from the compound are attached to the surface of the treated material by newly formed covalent bonds. The materials treated may comprise polyesters and co-polyesters derived from terephthalic acid and may be linear or slightly cross-linked or branched, e.g. by the incorporation of a tri-or tetrafunctional reactant such as glycerol, pentaerythritol or trimesic acid during manufacture of the polyester. The group in the applied compound which confers some desirable property upon the surface of the treated material may be a group which gives rise to hydrophilic and anti-static properties, absorbs or transforms ultra violet radiation, repels flames, kills fungi or bacteria or provides increased adhesion to rubbers, rubber latices, paints, inks or dyestuffs. The compound may also undergo other reactions either within single molecules or between molecules of the compound itself or with some other added component, e.g. another ester or polyester, at the same time as the reaction with the surface of the treated materials so that the chemical group attached to the surface although derived from an alcoholic compound R OH may not be the group RO but may be modified by the production of double bonds or ether or ester linkages. If the compound is susceptible to oxidation an antioxidant, e.g. thio bis-(3-methyl-6-t-butyl phenol) may be included in the treating composition.

Abstract: In electro-chemically grinding a conductive workpiece 10, e.g. of carbon steel or WC containing 6% Co, with a rotating tool electrode, e.g. a contoured graphite grinding wheel 12, electrolyte is applied to a machining surface 15 of the tool electrode, e.g. via nozzle 16, and excess electrolyte is stripped from the surface 15 prior to its juxtaposition with the workpiece, e.g. by squeezing and applying suction at the surface using a porous wiper 18 connected to a suction pump 20 and/or directing an air jet 22 thereagainst from a nozzle 23, to reduce the tendency to irregularly erode the juxtaposed surface. Preferably an organic surfactant such as olive or asphalt oil, stearic or caproic acid or cotyl alcohol may be added to the electrolyte, e.g. aqueous NaNO 2 + KNO 3 solution. For complex e.g. toothed or serrated profiles on the grinding wheel a complementarily profiled squeegee in the form of stiff celluloid, polyethylene or P.T.F.E. foil (130, Fig.6) may be used. Alternatively, a graphite wiper auxiliary electrode (518a, Fig. 9) may span the machining surface of the graphite grinding wheel to mechanically remove excess electrolyte and to electrically transform it. The electrolyte may be recirculated after replenishment. A.C. superimposed on D.C. may be used.

Title: Ignition distributors
IPC: F02P7/06
Filed: 1970-08-08
Abstract: A method of assembling an ignition distributor of the kind including a base plate which is secured to the casing of the distributor and a timing plate mounted for angular movement on the base plate, the timing plate carrying in use the contact breaker assembly of the distributor, including the steps of engaging the annular timing plate with the base plate. The base plate and the timing plate include mating surfaces which locate the timing plates for angular movement on the base plate when the timing plate and base plate are interengaged. Three tags or ears formed on the base plate are then deformed to overlie the surface of the timing plate remote from the base plate, the ears being such that any one of the ears is on the opposite side of a diameter of the plate from the remaining ears. The ears are bent to a position such that a predetermined clearance exists between the lower surfaces of the ears and the upper surface of the timing plate, so that the timing plate is held against disengagement from the base plate in an axial direction, but there is a predetermined amount of clearance between the ears and the timing plate, so that the timing plate is capable of small movements in an axial direction. In a first alternative the ears are deformed to the desired position prior to engagement of the timing plate with the base plate, and the timing plate is formed with slots through which the ears pass when the timing plate is engaged with the base plate. In a further modification the timing plate includes a plurality of projections onto which the ears are bent, the projections defining the extent of the clearance, and in a still further alternative the timing plate has projections which engage the base plate, and the base plate has apertures into which the projections can locate upon angular movement of the timing plate relative to the base plate. In this embodiment, the ears are deformed into engagement with the timing plate while the projections engage the surface of the base plate, and the timing plate is then rotated so that the projections locate in the apertures, and the predetermined clearance exists between the timing plate and the ears.
